How It Works

Fertile Window

Sometimes referred to as "Fertility Awareness" or "Natural Family Planning", fertility charting is based on the understanding that we can identify the fertile window- the days when conception is possible- by observing our natural fertility signals.

In each cycle there are just a few days that make up the fertile window.

Fertility charting with Fertility Friend thus involves observing and recording your fertility signs so that you can easily see your daily fertility status and identify your most fertile time. It is highly effective because your body provides clues (fertility signs) that tell you about your fertility status throughout your cycle.

A few minutes daily: Fertility Friend is extremely accurate. Based on your observations (it only takes a few minutes each day) Fertility Friend analyzes your data and provides you with an accurate interpretation of your fertility signs:

No data brokers or other type of data trade (referrals, etc). Fertility Friend does not consider your data for sale or trade in any way. Your data is not a currency at Fertility Friend.

Clear funding: Fertility Friend is totally funded by its premium features membership. This means independence and impartiality. You are Fertility Friend's customer and our loyalty is to YOU. If you do not know how a "totally free" App/Service is funded, or if you know it is funded with ads, referrals, or your data, you are likely the product that is sold, not the customer.

Health Data: Your health data is like a finger print. Even if "anonymized" it has the potential to identify you when cross referenced with other data. We do not engage in any data trade or referral for this reason.
